K2 - Wrong Q6 Driver?

JT Croteau
I am at the point where I need to install the driver at Q6.  The
manual states that I should have a 2SC2166 for the driver.  However,
included with my K2 6233 is a 2SC5739.  The parts list in Appendix A
of my Rev G. manual does not list any alternatives.

Anyone have any insight?

Thanks

JT,

Install the 2SC5739 at the Q6 location.  The part has been changed for
RoHS considerations, but the paperwork in the form of an errata sheet
did not catch up yet (no doubt due to the enormous workload of the K3
release).

Actually in the two K2s I have built recently, the 2SC5739 worked
slightly better than the previous 2SC2166 - it seems to have a bit more
available gain.
